PRO (1): Mohsen Askary
When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.
How to tell the difference between "easy" and "pro" questions:
An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)
A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).
Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.
When deciding between easy and pro, err on the side of pro. Most questions will be pro.
* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

page 6 مطالعات و تحقیقات کافی و عدم به کارگیري روشهاي مناسب طراحی، بسیاري از سدهاي ساخته
شده با مشکل تراوش غیر پیشبینی شده مواجه میشوند. در اینگونه موارد فرایند اصلاح و ترمیم
جهت معضل تراوش بهکار گرفته میشود. اجراي پرده آببند تزریقی، احداث پوشش نفوذناپذیر
بالادست، اضافه نمودن زهکش و... از جمله موارد ممکن در کاهش تراوش به شمار میروند.

GeoStudio میباشد و براي محاسبه مقادیر نشت به کار میرود، استفاده میشود. با توجه به میزان
آورد رسوب، پخش آن، آورد رودخانه و برنامهریزي منابع آب در هر سال و بلکه در هر نیمسال، ارتفاع
آب و ارتفاع رسوبات در هر نیمسال از چند سال اولیه محاسبه شده و مقدار نشت آب از پی در حالت
هاي وجود رسوبات با دیوار آببند و بدون دیوار آببند محاسبه میگردد. از آنجا که این محاسبات در
فضاي دو بعدي صورت میپذیرد، با توجه به مقطع عرضی دره، تعدادي مقطع براي سد خاکی در نظر
گرفته شده و براي هر فاصله اي از عرض دره، یک مقطع به عنوان مقطع موثر انتخاب میشود، لذا
مقدار نشت آب براي کل سد به دست میآید. از مقایسه میزان نشت آب از پی براي حالتهاي
مختلف، بررسی اقتصادي هزینههاي احداث پرده آببند و هزینههاي هدررفت آب در حالت بدون
دیوار آببند، معین میگردد که کدامیک ارزش اقتصادي بیشتري نسبت به دیگري دارد

Grout curtains are commonly constructed under dams to reduce the seepage through the rock foundation. In the design of grout curtains, empirical methods have mainly been used since the introduction of dam foundation grouting. Although empirical methods have been used with success in several projects, they have their limitations, such as poor control of the grout spread, only an indirect consideration of the threat of internal erosion of fracture infillings in the grouted zones, and the risk of hydraulic jacking
